Each example below pairs a goal with the audience filter and content approach. For the underlying mechanics, see [campaigns](/customers/campaigns). ## Promote upcoming sessions to recent customers Goal: nudge people who've booked recently to look at what's coming up. * **Filter:** *Course purchase* with a date range covering the last 1–3 months * **Content:** Lead with a friendly hello, then list 3–5 specific upcoming sessions with dates and booking links * **Subject line:** *Your next session is waiting* or *New dates just released* Recent customers convert best — they remember you and trust the experience. ## Send a seasonal promotion Goal: drive bookings during a peak or quiet period. * **Filter:** Broad — recent or all subscribed contacts * **Content:** Clear seasonal offer with a date range * **Pair with:** An [auto-applied discount code](/pricing/discount-codes) so the promotion is frictionless at checkout Spell out the offer in the subject line — *15% off summer sailing* beats *Sailing news*. ## Send a campaign to a certain group Goal: targeted message to schools, families, members, or any tagged segment. * **Filter:** *Contact tag* — e.g. `school` or `member` * **Content:** Speak directly to that group's needs and language Tag your contacts proactively (in their profile) so segments are ready when you need them. ## Re-engage customers who haven't booked recently Goal: bring back lapsed customers. * **Filter:** Combine *Contact subscribed* (signed up more than 6 months ago) with *Course not attended in last 6 months* if available * **Content:** Lead with what's new since they last booked, then offer a small incentive * **Pair with:** A targeted [discount code](/pricing/discount-codes) tracked separately so you know if re-engagement is working Keep the tone friendly, not desperate — *We miss you* often works better than a hard sell. ## Promote add-ons, memberships, or related products Goal: turn one-off customers into repeat or higher-value bookings. * **Filter:** *Course purchase* on the gateway activity * **Content:** Position the next product as a natural step — a recurring [membership](/pricing/memberships) for someone who's booked three lessons, or a related [add-on](/activities/addon-setup) for an upcoming booking * **Subject line:** Match the recipient's stage — *Ready for your next level?* or *Make your trip a weekend* ## Audience-sizing tips Always check the audience count before sending: * **Too many recipients** — your filters are too broad. Add a date range or a tag. * **Too few** — relax a filter, or check that contacts are actually tagged or subscribed. * **Zero** — almost always a filter logic issue. Toggle between *All conditions* and *Any condition* to see what changes. ## Related guides Build and send the email itself. Manage your contact list and tags.
